Perth seawater desalination plant, Australia
Totally Integrated Automation performs positively at Australia‘s first seawater desalination plant, the largest seawater reverse osmosis plant powered entirely by renewable energy, and wins PACE Zenith Award for Automation
The requirements Perth, the capital of the state of Western Australia, is particularly affected by droughts that have not only endangered the drinking water supply, but have also led to severe economic losses. To cure this problem, the Water Corporation of Western Australia decided to build a seawater desalination plant using reverse osmosis technology for better energy efficiency and a more compact footprint compared to a conventional thermal desalination plant. The undertaking was awarded to a joint venture between Suez Degrémont S.A. and Multiplex Engineering Pty as a private operating agency project. The contract includes a 25-year term of operation and maintenance, with extremely high requirements for performance, availability, and profit-ability, in particular in the area of
process automation and energy efficiency. In addition, this largest project of its kind in the southern hemisphere had to be completed in just 18 months.
The solutionWith a capacity of 45,000,000,000 liters per year, Kwinana Beach supplies some 20 percent of Perth’s water requirements. Because of their success in many other desalination projects, SIMATIC PCS 7 and PROFIBUS were chosen for the plant’s process control system. The server, all con-trollers, and the PROFIBUS connection to the field instrumentation were designed with complete redundancy. Facility management is significantly simplified through the use of a SIMATIC PCS 7 Web Server that allows operating personnel to
remotely access all facility data. In terms of energy efficiency, several SINAMICS G150 frequency converters reduce power consumption by up to 50 percent compared to unregulated electrical drives, while ensuring that delivery volumes always meet the actual demand. For better motor management, SIMOCODE pro is applied in the Motor Control Centers (MCC).
The benefitsThe automation system is based on the principles of Totally Integrated Automation (TIA) and meets all re -quire ments of the operating agency. Programming, maintenance, and exchange of components even during operation are easy and efficient, thanks to a common profile for all instrumentation and electronic devices. In line with TIA philosophy,
8
comprehensive diagnostic informa-tion allows for predictive mainte-nance, which significantly reduces costs. SIMATIC PCS 7 allows access to all internal parameters from a single point, which also simplifies commis-sioning. Operations and maintenance staff added a PCS 7 Web Server to extend their coverage. The server gives them the tools to access plant data from off-site, in a secure envi-ronment. Besides providing plant parameters for optimization or report-ing purposes, this aids plant main-tenance, especially outside normal working hours. The performance and reliable future-orientation of the system have even impressed inde-pendent experts: PACE, Australia’s leading magazine for process control technology, honored Perth-Kwinana with its Zenith Award for the best automation project of 2007.

Seawater desalination plant Valdelentisco, Spain
Totally Integrated Automation in Europe’s largest seawater desalination plant
The requirementsIn January 2008, Europe’s largest seawater desalination plant was completed in Valelentisco, located in the south of Spain between Mazarrón and Cartagena. The project was facili-tated by the A.G.U.A. program of the Spanish Ministry of Environment and will contribute to ensuring the drink-ing water supply and the agricultural irrigation in this water-scarce region. One of the requirements for the plant was the application of significantly fewer chemicals for pre-treating the seawater than in established plants. Furthermore, a fully-automated oper-ation with maximized process security and availability was required to guar-antee the highest possible supply security. In addition, through compre-
hensive research projects, energy consumption for seawater desalina-tion needed to be reduced by up to 30 percent in order to lower the costs for the water produced by up to 15 percent.
The solutionThe plant operates according to the Totally Integrated Automation principle. All processes, from the seawater pre-treatment up to reverse osmosis, are automated and con-trolled by the SIMATIC PCS 7 Process Control System. For extra reliability, all crucial system components have been configured redundantly. This is true for all servers and all controllers of the SIMATIC S7-400H line as well as the PROFIBUS connection of the field instrumentation via the SIMATIC ET 200M distributed I/O.
Access to all process data via the Internet is possible through the SIMATIC PCS 7 Web Server. An engi-neering station in the control room permits the centralized con figuration of all field devices ( process instru-mentation from the SITRANS product family and frequency converters) via the SIMATIC PDM con figuration soft-ware. The highly efficient H-compact motors and the installed SINAMICS and MICROMASTER frequency converters are major contributors to the plant’s operational efficiency. With these frequency converters, an energy reduction of up to 40 percent can be achieved compared to fixed-speed drives.
10
The benefitsThe Valdelentisco seawater desalina-tion plant is a fundamental pillar for efficient use of the resource water and thus sustainability. For its largest and most modern plant, operator Aguas de la Cuenca del Segura S.A. received an automation system that ensures maximum availability and virtually excludes any plant down-time. The redundantly built distrib-uted control system PCS 7 with its TIA philosophy provides not only a maximum of process security and plant availability, but also continuous transparency of the entire process, with consistent information regarding all process parameters up to the single field device or drive.

Seawater Desalination Plant Al Hidd, Bahrain
Siemens and Solution Partner EKIUM jointly provided and implemented SIMATIC PCS 7 control technology for the world’s largest thermal multiple-effect distillation seawater desalination plant to secure drinking water supply in Bahrain
The requirementsThe Kingdom of Bahrain, an archipel-ago in the Persian Gulf – with its 718,300 habitants – has immense water needs. Less than three percent of the land is naturally arable, so irrigation is a must. To satisfy the great need for water, Al Hidd Power Company (HPC) decided to expand the existing seawater desalination plant, more than doubling its capac-ity. Currently, it is the world’s largest thermal multiple-effect distillation (MED) plant, producing 400,000 m³ of freshwater every day (90 MIGD). Within the largest privatization project ever realized in Bahrain, HPC also took over the operational man-agement of the plant for 20 years. Since the commissioning of the new plant was to be carried out two years after the acquisition of the old plant, the capacity expansion had to be realized in the shortest time possible.
The solutionThe contract for the plant expansion was given to SIDEM (Société Interna-tionale de Dessalement), an affiliate of Veolia Water Solutions & Techno-logies. SIDEM opted for multiple-effect distillation (MED), where drinking water is gained through the evapo ration and the subsequent conden sation of seawater. The com-plex process management of the MED process requires an efficient and reliable distributed control system. After an intensive evaluation, SIDEM chose the Siemens’ distributed control system SIMATIC PCS 7 as the plant’s auto mation system and entrusted EKIUM (formerly Cira-Concept), a highly experienced SIMATIC PCS 7 system integrator and SiemensSolution Partner, with the engineer-ing and implementation. The
expansion project consisted of ten desalination units, which evaporate and condense seawater within a num-ber of vacuum chambers, separating the water from the salt. In this con-text Siemens delivered 33 H-compact motors for distillate, brine, and sea water pumps with a capacity of between 300 and 642 kW. Also in use are a cleaning unit, a hypochlorina-tion unit, a carbon dioxide unit, three boilers, a seawater pump system, and a metering system. These combine to produce an additional 273,000 m³ of water every day.
12
The benefitsSince its on-schedule completion in 2008, Al Hidd covers approx. 75 percent of Bahrain’s drinking water demand. A decisive criterion for SIMATIC PCS 7 was the option of complete hard- and software redun-dancy that guarantees maximum sup-ply security. Furthermore, the open-ness of SIMATIC PCS 7 allows the uncomplicated connection of external third-party systems. One example is a Profibus link to the boiler manage-ment system, another is the secure OPC-DA connection to the plant’s accounting system, which records the consumption data and forwards it automatically to the accounting department. Another important fact was the asset management system PCS 7 Maintenance Station because it provides troubleshooting diagnostic support through visualization of materials over the PCS 7 network. With this, highest plant efficiency and availability levels are ensured.

Water treatment project s-Hertogenbosch, Netherlands
A water treatment company in the Netherlands works to replace a multitude of incompatible legacy control systems with a single new automation concept for water purification
The requirementsThe Aa en Maas Water Authority supplies pure water and treats wastewater in the south of the Neth-erlands. It includes seven wastewater treatment plants and 107 sewage pumping stations, spread across five regions, covering an area of 1,162 square kilometers. Currently, in order to operate and monitor the installations, no fewer than 11 differ-ent control systems are used, a legacy of the piecemeal development of water treatment in the past. These “islands of automation” present the Aa en Maas Water Authority with significant difficulties. Workers often cannot transfer from one site to another without being retrained on the different systems, and there is no integration of the water treatment data with the management informa-tion systems of the head office.With a view to the future, the water authority decided to standardize the
water process automation systems and integrate them with its manage-ment information systems. This would enable it to automate its maintenance management and to compile produc-tion data over longer periods, facili-tating more accurate forecasting of future water treatment demand. The Aa en Maas Water Authority began by drawing up a supplier-independent master plan for process automation, which was reviewed with potential automation system suppliers. Follow-ing several rounds, Siemens was selected to be the systems and automation supplier for the water treatment automation project.
The solutionThe system proposed by Siemens was based on the SIMATIC PCS 7 Process Control System in combination with a SIMATIC S7-mEC (modular Embedded Controller) at every location. The
S7-mEC is a fully-fledged PC accommodated in the housing of a modular S7-300 CPU. The distributed SIMATIC S7-mECs function as pro-grammable logic controllers (PLCs) but communicate with a centrally located server in order to deliver all management reporting and visual-ization data. Process automation and office automation functions are combined in one platform. In a low-lying country like the Nether-lands, a system failure can have serious consequences. To achieve a service availability of 99.95 percent, the system employs a multilayer topology with redundancy at each layer. To reduce the risk of data loss due to network failures, the SIMATIC S7-mECs can communicate through both public telecommunica-tion networks and a backup satellite connection.
16
The benefitsThe great advantage of this project is its character of independence from people and place. Every sensor will be accessible from every site in the company, and every employee will have access to the process automa-tion system – also via tablet PCs. Depending on their function, staff members may also be able to control the system. Another great advantage is that adaptations will only have to be implemented once, whereas formerly they had to be programmed up to four times. Furthermore, the central, object-based library consider-ably reduces the chance of failure. The system will accurately monitor which adap tations have been carried out where, when, and by whom. This enables a faster and more efficient diagnosis of failures.

Water treatment plant Xiangcheng, Suzhou, China
Securing the water supply in one of China’s largest water treatment plants with Totally Integrated Automation
The requirements The city of Suzhou, located in the province of Jiangsu in Eastern China, has a population of approximately six million. The city‘s water treatment plant in the Xiangcheng district belongs to Suzhou Tap Water Com-pany. It has a designed capacity of 300,000 m³/d, and is the first highly automated water treatment plant to apply the leading water treatment technologies of ozone pre-oxidation and biological activated carbon treat-ment. The requirement was for an efficient and reliable automation system that would be easy to use and maintain. As an expansion of
the facility is planned, the installed system has to be scalable, open for and compatible with future system components.
The solutionSuzhou Tap Water Company chose system integrator Pacific Water Treat-ment Co., Ltd., which is a Siemens Solution Partner and a SIMATIC PCS 7 specialist. A core part of the plant is the distributed SIMATIC PCS 7 Process Control System. All key hardware components, such as the PCS 7 OS Server and the SIMATIC S7-400 H, are redundant. At the field level, SITRANS products for process instru-
mentation and energy efficient motors are implemented, along with ROBICON Perfect Harmony frequency drives for drive systems. Field devices are connected to control level via dis-tributed SIMATIC ET 200 I/O modules with Profibus DP connection. Thanks to TIA uniformity, all field devices can be configured in the central control room. Power distri bution is monitored and controlled via SIVACON electrical cabinets and motor control centers with SIMATIC HMI Panels.
18
The benefitsRedundant system design – from field level to control level – ensures high-est plant availability. The centralized process monitoring and control in the central control room, with its very intuitive operator interface, minimizes operational errors, while optimized data and process transparency help the owner to reduce operating costs. The application of high-efficiency motors also plays a part in this, while uniform SIMATIC products and tools offer significant time and cost savings during engineering and commissioning. Through the open and scalable architecture of SIMATIC PCS 7 and TIA standard-ization, future expansion will be problem-free.

Drinking water treatment plantRoetgen, Germany
Totally Integrated Automation with SIMATIC PCS 7 in Germany‘s largest and most innovative ultra-filtration membrane system for drinking water treatment
The requirementsThe WAG Wassergewinnungs- und -aufbereitungsgesellschaft Nordeifel mbH produces about 33 million m³ of drinking water annually and supplies the region around the city of Aachen, Germany. Unique to WAG, raw water from only four reservoirs in the northern Eifel region is used to pro-duce drinking water. The drinking water treatment plant (TWA) Roetgen, with its capacity of 30 million m³ annually, takes care of more than 90 percent of WAG’s water supply. To ensure future delivery reliability of drinking water, WAG decided to expand TWA Roetgen, so that highest-quality drinking water can be pro-duced even under extremely adverse raw water conditions. Because of the central importance of TWA Roetgen,
high demands were placed on its auto mation technology with regard to reliability and safety. At the same time, the total cost of ownership (TCO) needed to be reduced as much as possible.
The solutionAfter extensive preliminary investiga-tion, WAG decided to use membrane technology for raw water ultra-filtra-tion. To control the membrane mod-ules’ complex sequence of operations requires an efficient and very reliable process automation system that also relieves staff of time-consuming and error-prone routine work. Other deci-sive factors for WAG were long-term security of investment and the ability to set up a fully-redundant system
architecture in both control and com-munication channels – a prerequisite for the highest possible plant avail-ability. And finally, WAG chose SIMATIC PCS 7 as a key part of Totally Integrated Automation – with its highly efficient engineering environ-ment – which also enabled quick, easy, and reliable integration of SENTRON circuit breakers that are capable of communicating.
The benefitsSince project completion in 2005, WAG has profited from a future-proof solution offering high operational security and substantially reduced operating costs. Important for the system operator: The consistent use of the SIMATIC PCS 7 engineering tools throughout the entire project
20
enabled cost-effective project devel-opment. Using partially automated engineering at multiple levels made automation project development and implementation more efficient and less time-consuming. In addition, the communications capabilities of the implemented SENTRON circuit breakers made central monitoring and controlling of both the facility’s process technology and its energy distribution easy and efficient. TWA Roetgen is currently the largest drinking water treatment facility in Germany to use membrane tech-nology. Its successful commissioning has helped the trend- setting and innovative membrane technology make a large-scale breakthrough.

Integrated automation solutions – better utilization of domestic wastewater
23
Wastewater treatment plant Lüneburg, Germany
Modern control and telecontrol technology allow efficient operation down to the substations in the Lüneburger Heide
The requirementsThe wastewater treatment facility of the Abwassergesellschaft Lüneburg mbH (AGL) serves the northern German city of Lüneburg and six additional nearby towns. Daily, up to 25,000 m³ of wastewater from approx. 110,000 area residents and industrial and commercial customers are fed to the plant through a widely branching pipeline network. The facility not only treats the wastewater in a series of process steps, but also reuses the resulting waste materials, such as sludge and biogas, and im proves the water quality of the Ilmenau River, the largest of the small rivers that flow through the Lüneburger Heide (Lüneburg Heath). An efficient operation of such a com-plicated water management process requires a reliable automation system. When Siemens announced that it would discontinue the SIMATIC S5 controllers used in the facility, AGL decided on a complete replacement of its control technology.
The solutionSince the beginning of 2011, the distributed control system SIMATIC PCS 7 using SIMATIC S7 automation components, has been deployed. While the system was being modernized, the plant ran in parallel operation. To accomplish this, the system integrator GreyLogix Aqua first set up the new client/server architecture in the central control center and then installed a central automation system for data exchange between the old and new process control systems. When the individual parts of the plant were retrofitted, even the reporting system ran in par-allel: A continuous supply of relevant operations data to the logging system was assured until switchover. Thus, AGL could meet legal requirements for seamless data logging, long-term data storage, and report generation. An important part of the new control concept is the integration of 34 widely distributed remote plant sites: pumps, pumping stations,
and gauging wells. Actuators are still controlled using existing hard-ware; data exchange is managed by SIMATIC S7-1200 automation units. All large substations are equipped so that continuous monitoring of operations over an encrypted DSL connection is possible. Smaller sub-stations communicate using GSM. The telecontrol technology used in the central control center enables the communication of the substations with the centralized SIMATIC PCS 7 system and seamlessly merges the automation of centralized and distrib-uted process areas into one system. The data collected in the stations, the operating status of the aggre-gates, and the measured values from the pump stations are integrated into process screens, as well as message and alarm lists. This creates a consis-tent “look & feel” across the entire network with all its substations, in a familiar operating environment, making process control easier.
24
The benefitsThe modernization brought the central plant, as well as the remote stations up to a state-of-the-art level of technology. The selected control system was chosen for its ability to optimize plant performance and made a more flexible process control possible. The new plant and process technology saves energy during aerating of the aeration tanks and is more stable during abrupt weather changes. The connection of widely-distributed pump stations, the ability to access detailed information from the stations and their integration into operations offers clear benefits in efficiency and diagnostic tools. The data communicated about power usage and flow rate allows operators to draw conclusions about the status of individual pumps. Above all, the addition of more detailed monitoring and the seamless integration of the external stations using telecontrol assures more reliability in wastewater treatment and a more efficient opera-tion of the entire facility.

Czajka wastewater treatment plant, Warsaw, Poland
After modernization and upgrading with a SIMATIC PCS 7 process automation system, the Czajka wastewater treatment plant is Eastern Europe’s biggest and most modern plant
The requirementsWhen Czajka wastewater treatment plant (WWTP) was completed in 1991, after 17 years of construction, much of its technology and equipment was already outdated by the time the plant came online. To treat the waste-water of approximately 2.1 million people in the Warsaw area, a series of modern izations were started almost immediately. The Czajka upgrade and extension project is part of the Warsaw water supply and wastewater treatment plan, phase three of which includes the plant’s upgrade, the construction of a thermal sludge drying facility, new transmission sewers, the mod-ernization of the wastewater system, and the implementation of a modern monitoring and control system. The major goal of the plan is to up- grade the plant in order to increase wastewater treatment capacity from the current 240,000 m³/d to 435,300 m³/d, rising to a potential 515,000 m³/d at peak times.
The solution A key aspect of the facility’s modern-ization program involves a com pletely new distributed control system, the SIMATIC PSC 7 system from Siemens, providing comprehensive visualiza-tion, control, and monitoring of all processes involved. The design in cludes more than 50 controllers, two redundant SIMATIC PCS 7 OS Servers, five SIMATIC PCS 7 OS Clients as operators’ workstations, more than 1,000 analog measurements, and more than 2,000 drives. The SCADA automation and monitoring ensures optimal flow through the plant pro-cesses, providing full control and operational visualization, with real-time data measurement, equipment status, alarm notification, and system failure alerts.
Another significant plant improve-ment at Czajka is the thermal sludge treatment, which reduces the volume of material and facilitates its use as landfill. The new sludge combustion plant generates power and heat – and is also entirely controlled by the SIMATIC PCS 7 Process Control System from Siemens.
The benefitsThrough the completion of the Czajka upgrade and extension project, important aspects of the city’s potable water supply have been improved. In addition, the plant is now able to handle more than 300,000 m³/d of wastewater from the left bank of the Vistula River, thereby greatly improving water quality in the river, the city’s prime source of potable water, and ultimately reducing the contaminant load entering the Baltic Sea.

Wastewater treatment plant for the City of Kelowna, Canada
Upgrade and expansion of the existing APACS+ control system to the most modern distributed control system with SIMATIC PCS 7
The requirementsKelowna’s sewer system collects, con-veys, treats, and disposes of domestic and industrial wastewater from the rapidly growing city in the interior of British Columbia. The wastewater is conveyed to Kelowna’s wastewater treatment facility (WWTF), an innova-tive treatment plant utilizing cutting- edge UV disinfection processes and a state-of-the-art odor control system. The city’s wastewater system currently services close to 80 percent of Kelowna’s population and is being expanded to reach areas presently unserviced and to accommodate growth. Today’s capacity of 40 million liters of sewage per day will soon be reached, so an upgrade to the treat-ment facility will almost double this capacity to 70 million liters a day over the next four years. The city of Kelowna’s challenge was not only to upgrade their existing APACS+ operating and control system while protecting their original investment, but also to lay the foundation for their future control system, driven by the plant’s expansion.
The solution To achieve all this simultaneously, system integrators TURN-KEY CONTROLS suggested a step-by-step migration from the old APACS+ control system to the most modern SIMATIC PCS 7/APACS+ Operator System with minimal risk and highest return on investment. The first step was to replace the old IFIX HMI with SIMATIC PCS 7 OS. As a second step, new SIMATIC S7 controllers were used for site expansions and tied into SIMATIC PCS 7 OS. Future steps of the migration include replacing the APACS+ ACM controllers with SIMATIC S7-400 controllers, using DP/IO link to tie in the APACS+ IO into SIMATIC S7-400 controllers, and replacing the APACS+ IO modules with SIMATIC S7 IOs. The City of Kelowna project proves Siemens’ continued commitment to support and improve APACS+ systems currently installed worldwide.
The benefits The step-by-step migration concept holds numerous benefits for the operators. First, the new system is a secure investment, since even-tually all APACS+ products will be replaced by a modern, future-proof SIMATIC PCS 7 product. Second, the concept prolongs the life of currently installed APACS+ assets (both control-lers and IOs), thus reducing the cus-tomer’s investment to the necessary minimum. And, since the old system serves as a backup in parallel as long as the new system is being commis-sioned, the switchover requires little to no system downtime. Apart from this, the concept allows upgrading the system along the customer’s own timeline and the available capital, while the customer profits from shorter lead times and increased plant produc tivity, thanks to the use of Totally Integrated Automation (TIA) and SIMATIC IT in their processes.
28
In practice, the new distributed control system SIMATIC PCS 7 offers significant functional enhancements and improvements compared to the existing control system. These include SFC visualization (Sequential Function Chart) for sequential control at the operator station, asset management for improved diagnostics and pre-ventive maintenance, and a process device manager for central parame-terization and configuration of intelligent field devices. As a result, operator efficiency is improved, and maintenance cost and the overall cost of ownership are reduced. Furthermore, SIMATIC PCS 7 paves the way for vertical and hori zontal integration from field to the MIS/MES levels, while the Web server allows the operator system to be published on the Internet for remote monitoring and control.

Automation of the Oguz-Gabala-Baku water pipeline, Azerbaijan
Siemens helps secure water supply in Baku, the capital of Azerbaijan, by implementing automation solutions in the new water transport system
The requirements The Oguz-Gabala-Baku water pipeline project dates back to plans from the 1970’s. Baku’s growth was historically driven by the booming oil industry and required the import of drinking water from outside of the city. Before the construction of the pipeline, some 60 percent of the city’s households received water for only a few hours daily. After completion of the project, 75 percent of the two million Baku residents are now served around the clock with potable water, based on World Health Organization (WHO) standards. The 262-kilometer pipeline requires no pumping station, but uses the altitude differences between the Caucasian mountains and the capital to supply 432,000 m³/d to the Ceyranbatan water reservoir. To the people of Baku, the pipeline is “the most important project not only in 2010, but of the last 20 years.”
The solutionThe project was realized in coopera-tion with CASPEL, a regional system integrator specializing in solutions for data transfer, software development and supply, and maintenance of state-of-the-art IT hardware and software from leading manufacturers. Siemens supplied the automation technology for the pipeline project. For the comprehensive monitoring of water pipes and avoidance of potential emergencies, CASPEL installed a SIMATIC WinCC control and data management system. CASPEL adjusted the connected IT system and ensured that global standards were met. Major recon-struction work was carried out at various sites of Baku’s water system. The Siemens automation solution is based on the SIMATIC product suite: SIMATIC S7-1200 and SIMATIC S7-300 were installed for the control of the
pipeline gate valves and in order to collect the flow meter data for leak detection. The flow meters were implemented with SIMATIC PDM. The HART protocol was applied for the relevant communication. The visu-alization and supervision of the entire plant was realized based on SIMATIC WinCC. The SIMATIC S7-300, positioned at the 75 wells in the higher region, communicate via GPRS modems with the redundant SIMATIC WinCC OS Servers in the central station, while the different stations along the pipeline are con-nected by redundant fiber optic cable ring.
The benefitsThanks to the application of the SIMATIC automation technology that has been proven in numerous opera-tions, Siemens was able to provide increased functional reliability for the
32
entire plant. Thanks to using decen-tralized SIMATIC S7-1200 and S7-300 with Telecontrol via GPRS, all compo-nents of the 262 km pipeline can be operated and monitored with WinCC. Existing components were easily integrated via OPC. In addition, the operator benefits from full plant transparency, thanks to state-of- the-art communications technology, and early fault detection through better diagnostic functions, such as reporting and archiving of leak- detection system alarms, etc. Higher transparency also pays off in terms of a more secure investment, as troubleshooting is greatly acceler-ated, for example in case of an emergency pipeline shut-off. By implementing Siemens’ stringent international project management standards, the project was realized on time, within budget, and with an outstandingly high quality of work.

ISKI Asia Zone pump stations, Istanbul, Turkey
Siemens supplies five pump stations for the extended water supply network of Istanbul
The requirementsISKI, the Istanbul Water and Sewerage Administration, is part of the Istanbul municipality and is responsible for the administration and operation of the water distribution, sewer net-work, and infrastructure of waste-water treatment. About 13.2 million inhabitants are connected to an infra-structure comprising 12 wastewater treatment plants and a 16,900 km water distribution network.
Due to the steadily growing population of Istanbul, the water and wastewater infrastructure had to be extended. As a consequence, the project was started with the objective of modernizing the existing pump stations and constructing new ones, in order to connect a further one million inhabitants of Istanbul.
For the realization of the project, ISKI looked for reliable equipment and solution providers as a success factor for secure and uninterrupted water supply. As a long-standing supplier of ISKI, Siemens was selected as the solution provider for local control stations, medium- and low-voltage installation, as well as drives and related equipment.
The solutionSiemens Turkey supplied the electrical solution for all pump stations of the project. The quality of work was ensured by Siemens supervisors and experienced commissioning teams. Fulfilling the requirements of ISKI, Siemens Turkey designed the single line diagrams and panels. In a second design step, the regional Siemens engineering department selected the pump drives according to the appropriate water pressure, operation philosophy, and efficiency. For the
medium voltage supply, the Siemens SIMOPRIME solution was selected. The power supply system was designed with the various summer and winter time load curves in mind. The existing, modernized pump stations as well as the new ones were integrated into the central control desk system, which was also part of the overall design solution.
In order to support failure-free operation of the pumps, Siemens installed SITRANS-L type ultrasonic level sensors for water level super-vision in the different supply zones. The technical solutions of Siemens followed the standards defined by TSE (Turkish Standards Institute) and TEDAS (Turkish Electricity Distribution Corporation). Furthermore, the tech-nical solution was aligned with ISKI and the Istanbul Asia Site Electrical Authority (AYEDAS).

Jacksonville water supply project, Florida, USA
Siemens helps utility JEA keep the waters flowing in Northeast Florida by introducing SINAUT telecontrol
The requirementsJEA is responsible for electricity, water, and sewer services to the resi-dents and businesses of Northeast Florida. JEA’s water system serves more than 305,000 water customers and 230,000 sewer customers and comprises 4,208 miles of water lines as well as more than 3,760 miles of collection lines and seven regional and eight non-regional sewer treat-ment plants.
Siemens’ challenge was the modern-ization of the outdated pumping control system for the 1,273 lift stations that keep wastewater flowing through 14 treatment centers and help JEA manage storm water flows. In addition, the new automa-tion system needed to be capable of controlling additional pumping capacity and communications, as JEA continues to acquire adjacent water systems and connect current septic tank owners to their system.
The solutionTo supply modern capabilities and ensure easy expansion, Siemens installed an automation solution based on a SIMATIC S7-300 with SINAUT ST7 telecontrol, SIMOCODE pro V motor management, and SIMATIC WinCC HMI. The SIMATIC S7-300 system provides local logic as well as data collection for the SINAUT ST7 and is also the Profibus master for two SIMOCODE pro V systems that provide motor overload protection, local I/O to read in the analog well level, and the digital floats’ signals. If the PROFIBUS con-nection is lost, the SIMOCODE pro V provides redundancy and takes over full control of the pumping operation until the network is restored. In addi-tion, SIMOCODE pro V also provides key diagnostic and operational data to the control center, which can be used to evaluate system performance.
The SINAUT ST7 extends the SIMATIC S7 automation system by integrating special hardware and software components. This enables remote data transmission. In order to provide fully monitoring and control, the SINAUT ST7 provides a reliable data transfer between the lift stations and the master control center. In case of connection failures, the respective SINAUT ST7 buffers the data and transmits it as soon as the connection is restored. Thus, SINAUT ST7 enables fast access to all lift stations and central, complete data collection in SIMATIC WinCC. For high reliability, a SITOP DC UPS system provides backup power.
The benefitsThanks to the new automation system, JEA can use two-way com-munications capabilities with the SINAUT ST7 for remote diagnostics, software upgrades, and other fixes and maintenance that would other-
36
wise have to be done onsite by a technician while maintaining commu-nications with any other RTU on the system. In addition, energy savings are realized by using pumps in con-cert rather than having them pump against each other. And thanks to the automatic diagnostic logs of all communications between the central control system and the remote lift station, along with details of the type and time of any failures, trouble-shooting is substantially accelerated. In addition SIMOCODE pro V provides extra peace of mind, since it keeps the lift station pumps working even if the PLC control network goes down.
